India notifies standards for petrol blended with up to 30% ethanol, as part of the government’s ongoing ethanol-blending programme. The development follows India’s rollout of E20 ethanol blending and signals a move toward higher ethanol content in petrol in subsequent phases. According to reports, the government’s schedule for increasing ethanol blending advances the 20% target: the timeline is moved forward from 2030 to 2025–26, indicating faster implementation of higher blends. In parallel, the Bureau of Indian Standards (BIS) issues the technical groundwork for fuels with ethanol levels in the range of E22 to E30. This includes establishing specifications and related standards needed for the availability and use of these higher-ethanol blends in petrol-powered vehicles. The notifications are presented as a framework step that supports the transition beyond E20, while the eventual impact on vehicles and fuel systems depends on compliance with the newly notified standards and vehicle compatibility with higher ethanol concentrations.
